Robbie Neilson insists that he's still looking for the final pieces of his first-team jigsaw but he won't be rushed into signing the wrong personnel.
The Jambos head coach has already brought in five new bodies to complement the existing young talent at the club, and although he's keen to add another couple of faces he will only sign the "right ones".
Speaking to HeartsTV after Hearts' friendly match against Hamilton Academical last night, Robbie said: "There is still room to manoeuvre in the transfer market. We're still looking to bring one or two in.
"There's still time. I'd like to get things done quickly and give them time to settle in - whoever comes in - but sometimes you need to wait for the right ones."
One of those new faces could be Prince Buaben. The former Dundee United midfielder linked up with the Jam Tarts at their training camp down south and has featured in the last two friendly matches. Robbie says that although no deal has been struck, something could yet happen.
"Prince is up and has been training with us," he said. "He met us down in Leigh, trained there and came up on Tuesday to train some more. He played last night and he's just kind of proving his fitness right now.
"He's got undoubted ability. Hopefully if he does prove his fitness then we can do something about it."
Hearts went down 1-0 to Accies at New Douglas Park last night thanks to a last gasp Grant Gillespie goal. Despite the scoreline, Robbie thinks there are plenty of positives to see.
"It was a good exercise," he said. "It's about working on our fitness and trying to implement some things that we're trying to work on at the training ground at this point of the season.
"There's still a long way to go but we're getting there."
